What do you think the meta-crisis doctor's life would be like ?

Ive thought about this quite a lot too. I think, since the meta-crisis doctor has all of the real doctor's memories with rose, that he and rose will be happily living together and married. I also think he and Rose will be working together in torchwood and will have built their own tardis with their own piece of coral from the doctors tardis. Im not sure about family though- is Rose that sort of woman to be a mother?

"Rose is actually happy in the parallel universe with her half-human Doctor." -Russell T. Davies

So I guess they just live out their lives as a normal couple, Rose and TenToo! I like to imagine it as a weird sort of rom-com story, with Rose having trouble adjusting to TenToo at first, but they fall in love and she stops thinking about the "real" Doctor so much and stops thinking of TenToo as someone she has to settle for and more as someone she really loves. I don't think they'd build their own TARDIS or do much more than help out at Torchwood, because that would be like trying to chase the life of the Doctor and the two of them wouldn't want that. They're separate from him and happy. ^_^

Well, actually i wish he fell with a other girl, i not saying that i wish him to forget Rose.
I don't he will join Unit or Torchwood, because he hates them.
